The Metal Shaft (メタルシャフト Metaru Shafuto) is an extendable quarter staff used by Kamen Rider Double when he assumes any form that uses the Metal Memory. It first appears in Kamen Rider Decade: All Riders vs. Dai-Shocker, and then made its TV debut in episode 2.
Metal Shaft can also combine with Double's Memory Gadgets as well.
- HeatMetal - Metal Branding (メタルブランディング Metaru Burandingu): Double causing one or both ends of the Metal Shaft to ignite on fire and deliver a final blow to the opponent. A variation of this attack is the Steam Metal Branding (スチームメタルブランディング Suchīmu Metaru Burandingu), a tandem attack used in combination with Kamen Rider Accel's Engine Blade which is only seen in the Hyper Battle DVD.
- CycloneMetal - Metal Twister (メタルツイスター Metaru Tsuisutā): Kamen Rider Double spins around while swinging the Metal Shaft covered in an aura of wind.
- LunaMetal - Metal Illusion (メタルイリュージョン Metaru Iryūjon): Kamen Rider Double spins the Metal Shaft around to create golden rings that float around Kamen Rider Double, before unleashing them upon the target all at once.
When Stag Phone attaches to the Metal Shaft, it allows Kamen Rider Double to perform the Metal Stag Break (メタルスタッグブレイク Metaru Sutaggu Bureiku) Maximum Drive, crushing the Dopant between two pincer-like energy projections emitted from the Metal Shaft.
Finishing his battle with Nobuhiko Tsukikage in the World of Decade, Double assumed HeatMetal and used the Metal Shaft to send Shadow Moon flying into the Dai-Shocker Castle, leaving him to be destroyed with the Castle by the All Rider Kick.
Having been summoned to the world within the Magic Stone by Haruto, Double assumed HeatMetal and wielded the Metal Shaft against a trio of Masquerade Dopants while Fourze fought three Stardust Ninja Dustards.
